EMBROIDERY-HOOP ADJ USTER.

Application led November This-invention relates to new and useful ii'nprovements in adjusting devices, and particularly to devices for adjusting embroidery hoops. V

One object of the invention is to provide an adjusting device for this purpose which is simple' in construction, easy to operate, and which can be manufactured at a comparatively low cost.k Y

Another object is to provide a device of this character which has no parts with which the fabric, or the embroidering thread may become entangled.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of a portion of an embroidery hoop showing the invention applied thereto.

Figure 2 is an enlarged vertical sectional view of the parts shown in Figure 1.

Referring particularly to the accompanying drawing, 10 and 11 represent the ends of the embroidery hoop, in connection with which the present inventionl is especially adapted for use. These ends 10 and 11 are disposed in the ends of a flat tubular guide member 12, said member having the registering elongated slots 13 and 14, inthe upper and lower sides. Disposed outwardly of the meeting ends of the hoop is an elongated casing 15, longitudinally through which is formed the bore 16, and. formed transversely through the intermediate portion of the casing, and intersecting the bore, is an elongated opening 17. Formed on one end of the casing is an arm 18, which is bent to dispose `its outer end on the end 1() of the hoop, where said arm is secured to the hoop by rivets. The extremity of the arm is formed with a point 19, which is buried in the hoop end, so that there will be no proj ectingpart for thread to catch upon. Secured to theother end of the hoopis a similar arm 20, and said arm has its other end threaded andv disposed through the before-mentioned bore 16, of the casing 15.k

6, 1925. Serial No. 67,378.

Engaged on the threaded portion of the arm 20, and having portions of its periphery pro- `jecting through the opening 17, is a nut 21,

the peripheral face of which is roughened i to facilitate turning thereof. Formed on the casing 15, and extending into the adjacent opening or slot 13, of the tubular guide member 12, is a lug 22, which is upset inwardly of said tube, whereby said casing andl clamp the hoop against the fabric, and the Y inner hoop 23.

It will be noted that the entire adjusting mechanism presents a perfectly smooth eX- terior, thereby obviating the annoyance of the emhroidering thread catching on the de` vice. Furthermore, the device is adapted to be easily attached to the ordinary embroidery hoop, without modifications thereto.

The guide 12 is preferably seamless, therefore the necessity of the provision of the opening 14, to permit introduction of a tool to upset the lug 22. v

1V hat is claimed is:

A device for expanding and contracting a ring including a casing having an integral arm attached to one end of the ring and having a bore, an arm attached to the other end of the ring and having a threaded portion disposed in said bore, a nut on the threaded portion of the arm and projecting through the casing, the casing having an integral lug, and a tubular guide receiving the ends of the ring therein andvhaving an opening in which said lug is upset.

Intestimony whereof, I afliX my signature.

GEORGE H. BRUDER.
